P. HILLARD AND JOHN HAGKALEY, BOTH OF SPINNING-MULE.

SPECIFICATION forming part of Letters Patent No. 357,990, dated February 15, 1887.

. Application filed February 2, 1886. Serial No. 190,567.

To all whom it may concern.-

Be it known that 1, WILLIAM HAOKALEY, of Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Spinning- Mules, of which the following is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification.

My invention relates to the class of spinningmachines ordinarily known as the Mason Mule, which is described and illustrated in detail in United States Letters Patent No. 4,779, dated October 3, 1846, and to which reference may be had in connection with this specification.

The object of my invention is to secure a clear back-off motion, so that the thread is completely uncoiled from the spindles, whereby a more perfectly wound cop is obtained. Fun ther, my invention obviates the evil results of the rebound of the ball, whose oscillations throw the belt guide or shipper across the series of the fast and loose pulleys.

To the above purposes my invention consists in providing the belt-shipping means with a yielding-or delaying device for effecting a delay in the shipping of the driving-belt over the pulley series and controlling the gradual adjustment of said belt, whereby I am enabled to perfectly control the period of time requisite for the back-off motion, and so obtain a perfect and clear motion, all as hereinafter fully described and claimed.

In the accompanying drawings, Figure A represents a side elevation of the main part of the mule-head with my improved delaying belt-shipper attached. Fig. B represents a detached and enlarged top view of my beltshipper with the friction-thrower arm and the pulley series on a portion of a shaft lying beneath. Fig. 0 represents a side perspective of a modified form of my device with the friction-thrower arm and the pulley series in part .lying beneath. Fig. D represents an enlarged (No model.)

Fig. F represents a top plan view of a portion of the mule-head, shown partly in full and broken lines and partly in section. The view shows the relative arrangements of the balanced oscillating ball, my improved delaying belt-shipper, and the coacting frictionclutch mechanism which governs the backingoff motion, as hereinafter described.

' In the accompanying drawings like numbers designate like parts throughout.

My invention pertains merely to the beltshipper, or means for changing the motion of the mule and its indirect influence upon the back-oft motion, and will be described with the immediate parts of the mule which it afl'ects.

Referring to the drawings, 1 designates the first fast pulley, which serves to indirectly operate the drawing-rolls to deliver the yarn and the running out of the carriage (notshown) when the driving-belt is shifted onto said pulley. The second fast pulley, 2, when carrying the driving-belt, indirectly operates the winding of the spindles and the running in of the carriage. Between the said running out and in pulleys is mounted the loose pulley 3, and the machine is at rest while the drivingbelt remains on the same. This series of pulleys is mounted and operate in the well-known manner of the Mason mule, the motions of which are classed in three series, as described in the above-allnded-to patent. The second series of these motions comprise the backingoft motion, and it is this motion that I seek to influence indirectly by myinvention, as hereinafter described.

The belt-shipper 4. consists of the flat arm 5, which runs from one of the fiat sides of the belt-guide eye 6, curves downwardly, then runs straight outwardly, where, near its end, it is provided with an eye, 7. From the side of the eye 6, opposite the arm 5, springs the bridge 8,which is flat and curves over the pulley series, and has at its end the large rectangular eye 9. This eye 9 is quite large, and has its larger portion extending to one side of the bridge 8, as shown in Fig. B, and at this side it has the crossbar 10, held in position by small bolts 11, taking through the long sides into said bar, which has a channel, 12, through its center. The cross head 14 and shank 13 ICO compose a T-shaped slide, the former part being countersunk on its outer ends to track on the long sides of the eye 9, and the latter part taking loosely into the channel 12 of bar 10. At the free end of the shank 13 is a small check-pin, 16, which limits the inward travel of the slide 13 14, so that the limit of traverse of said slide equals the distance between the inner face of the bar and its contact-face on cross-head 14, as shown in Fig. 1B. The spiral spring is coiled around the shank 13, and

' its ends bear against the cross-head 14 and bar. 10, respectively, and normally keeps the slide 13 let in the extended position shown.

On the side of eye 9, opposite to and in a line with bridge 8, is the fixed stud 17, which engages with the weighted balance lever or ball 18, which is actuated to fall from an upright position, alternately to one side and then the other, whereby the ball is operated to throw the belt-shipper 4, by means of stud 17, in guiding the belt over the series of pulleys, after the manner described in the abovereferred-to patent.

The belt-shipper dvibrates on the fixed pin 19, passing through eye 7 and down through the friction thrower arm 20, which turns thereon. This arm 20 is of ordinary construction, having the screws 21 to adjust the play of its stud 22, which works in the usual friction-thrower, as shown in Fig. 1 and this thrower effects the clutching and unclutching of the friction-clutch 23, as will now be de scribed. The friction-clutch 23 is keyed on the rotary shaft 4L6,which is loosely journaled in the side framesAS, as shown, and is capable of endwise movements in its bearings. The friction clutch pulley 49, which carries the spindle-actuating band,(not shown,) is loosely mounted on the shaft 46, and is arranged to be clutched and unclutched by clutch 23,when said shaft is reciprocated longitudinally, in a manner well known. The pinion-wheel 50 is keyed on shaft 46, and is designed to be in mesh with a set of intermediate gears, which in turn mesh with what is called the top sliding rack, which controls the backing-oif motion, as set forth in the above-cited patent. The fixed collars 51 on shaft 46 are engaged on their opposite faces by the foot 52 of the friction-thrower, which consists of a straight cylindrical stem, 55, provided with a foot, 52, at the lower end and a notched head, 53, oppositely disposed upon the upper end of said stem. Thefriction-thrower is suitably mounted, so as to turn on the long axis of the stem 55, and the notch in the head thereof is engaged by the stud 22 of the friction-thrower arm 20. In an obvious manner the movement of the belt-shipper controls the friction clutch to clutch or unclutch, according as the the opening in eye 9, and back to startingpoint. .Vhen the ball falls and throws the shipper 4 over the fast pulley 1, the belt is guided thereon and bears against therigid end of eye 9, corresponding to bar 10, and the mule performs its first series of motions. The second series,eomprising the back-off motion, occurs during the period of transition of the shipper from over pulley 1 to pulley 2. Ordinarily this period is too brief to allow a clear back-off motion, since the belt is suddenly shifted from the running-out to the runningin pulley. By my device, when the ball falls and endeavors to shift the belt from pulley 1 over to pulley 2, it cannot do so immediately, because the belt bears against the yielding bearing afforded by the slide 13 14., This slide,itis obvious, will by this motion be driven down against bar 10 and its spring compressed to its greatest tension, and the spring gradually extending itself to normal position will graduate the adjustment of the belt onto pulley 2, which now makes the third series of motions for the mule. During this gradual guidance of the belt onto the running-in pulley the back-off is being completed and the friction-thrower arm 20 is being gradually operated to indirectly effect the clutching of the friction-clutch 23 in such a way that when the belt is well onto the running-in pulley 2 the clutch is secure against possible slipping. It is this slow and retarded adjustment of the belt upon the running-in pulley that is the chief object of my invention.

In the modified forms of Figs. 0, D, and E, I show a co-operating pair of shippers with the yielding or graduating construction arranged about the pin 19,which is here longer, and upon which vibrate the pair of shippers 26 and 31 and their friction-thrower arm 20. The upper shipper, 26, is of the ordinary form, but without the stud to engage with the ball, and has upon thelower face and to one side of its eye 27 the lug 33,which depends into the eye 32 of the lower shipper,31. This eye 32 is cut away on one side, as shown in Fig. 0, to allow the lug 33 to pass laterally in and out of the eye 32. The shipper 31 is arranged and constructed as ordinarily, except that one side of its guide-eye 32 is cut away. The stud 34 is designed to engage with the ball which operates to throw the shippers over the pulley series 1 2 3. Around the pin 19 is placed the spiral spring 30, the lower end of which is fixed to the end of shipper 31, and the upper end is fixed to the collar 29, which is made fast to shipper 26. hen the ball falls and throws the stud 31 over the fast pulley 1, both shippers 26 31 move together by virtue of the lug 33, and guide the belt at once onto the said pulley, and the spring 30 is not tense. \Vhen the ball throws the stud over fast pulley 2, the shipper 31 at once follows, the lug 33 coming out of eye 32 and leaving the belt behind, to be subsequently brought over by the solid eye 27 of shipper 26, which is then slowly forced over to the pulley 2 by the ac" IIO 19, and its free end bears against a lug, 37,-

with a small adjusting-screw, 38, fixed upon the under side of shipper 26. This form operates in the same way as that of Figs. 0 and D, the actuating-spring being under greatest tension when its shipper 26 is alone over the running-out pulley 1.

It will thus be seen that in allforms of my belt-shipper the driving-belt is eased gradually onto the running-in pulley by a yielding bearing influencing the belt.

In the usual form of spinning-mules the driving-belt is thrust directly onto the running-in pulley from the running-out pulley, and this sudden starting in of the carriage does not afford sufficient time for the spindles to reverse and uncoil the coil of yarn, which is borne down by the fallers, and thus to complete the back-oft motion. This is a serious defect, and this imperfect back-off always leaves the slack to be built into the cop, which is necessarily badly .formed, being too loose for good spinning purposes. Moreover, the old form of mule allows the carriage to start to run in before the friction elutch is securely and firmly clutched against slipping, and the resulting slipping always tells by tightening the yarn on the spindle, which is of course affected thereby.

By virtue of my delayed and gradual adjustment'of the belt by the shipper I obviate the defects of an imperfect back-oft by making a clear back-off, and the defects of the friction-clutch slipping on itself and the rebound of the ball by having the clutch securely adjusted against slipping.

By delayed guidance of the belt onto the runningin pulley the old device known as the regulator can be dispensed with entirely, and I can obtain a clear bacleoff, thereby securing a very tight cop-nose.

There may be various modifications made in my device'to accomplish the delayed gradual guidance of the belt by the shipper, as described, without departing substantially from the spirit of myinvention, as herein described and claimed. For instance, by means of a similar use of an equivalent delaying device, the same end may be accomplished as I now reach.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with means for shipping a drivingbelt, of a delaying device, substantially as described, engaging the drivingbelt and acting to delay the shipping of the driving-belt, for the purpose herein set forth.

2. The combination, with a belt-shipper oscillating over a series of pulleys, of a delaying device, substantially as described, directly engaging the driving-belt, whereby the beltshipper may act to ship the driving-belt one way with a delayed action and the other way with a prompt or positive action, for the purpose herein set forth.

3. The combination, with a belt-shipper and the series of pulleys in a spinning-mule, of a delaying device, substantially as described, engaging the driving-belt, the clutch and its controlling mechanism, and connections intermediate of said beltshipper and mechanism, whereby the belt may be shipped onto the running-out pulley with a prompt or positive action and the clutch be unclutehed, and whereby said belt may be shipped onto the running-in pulley with a delayed action and the clutch be clutched, for the purpose herein set forth.

4. The combination, with the belt-shipper of a spinning-mule and the actuating means therefor, of a spring-acted delaying device, substantially as described, engaging the driving-belt and co-operating with said shipper, whereby the'driving-belt may be shipped the one way with a positive action and the spring remain unstrained, and whereby the said belt may be shipped the other way with a delayed action and the spring be made tense or strained, for the purpose described.

5. The combination, with a belt-shipper provided with a belt-guide eye, of a movable member disposed in or near said eye and pro vided with a spring, substantially as described, whereby the belt-shipper may be moved the one way and ship the belt with a positive action, and may be moved the reverse way and ship the belt with a delayed action, substantially as and for the purpose herein described.

6. The combination, with the belt-shipper provided with a belt-guide eye, of a sliding spring'acted member or slide disposed in or near said eye, substantially as described, and acting to push upon the driving-belt, for the purpose herein set forth.

7. The combination, with the shipper 4, provided with the extended guide-eye 9, of the spring-acted T-shaped slide 13 14, substan' tially as described.

8. The combination, with the shipper 4, consisting of the arm 5, the guideeye 6, the bridge 8, and the eye 9, and the stud l7, ofthe spring-acted T-shaped slide 13 14, substantially as and for the purpose described.
